• Cannot access Nagios Web Interface

  - by Dominiqs

  After successfully installing Nagios core 3.4.1 (i also installed plug-in1.4.11) on our linux rhel 5.3 server i cannot login to the nagios web interface.I am running apache 2.2.3 I am using internet explorer 8 and also firefox 3.6.3 When i try to enter the url http//localhost/nagios/ on a desktop (on the same network as the Nagios server)it does seem to like it but if i try http//x.x.x.x/nagios/ (where x.x.x.x is the IP address of my nagios server) it likes it but then the authentication popup appears after entering the password and username(nagiosadmin) it throws the errors below The server x.x.x.x at Nagios access requires a username and password Warning this server is requesting that your username and password be sent in an insecure manner(basic authentication without a secure connection) After a few attempts i get error 401 authentication required error from internet explorer ;this server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials or your browser doesnt understand how to supply the credentials required. Help Please anyone..seems like an authentication issue

• using main domain as a mail server

  - by zensys

  I have a mail server set up as mail.mydomain.com like most people do. Now I find out that if I want to secure both mail.mydomain.com and mydomain.com with ssl I need two SSl certificates (or one more versatile but more expensive certificate). Does it make sense to run my mail server under mydomain.com (it is the same physical machine anyway) to save certificate expenses (I am Dutch) or is this being pound foolish? What is the rationale of separating the mail server from the 'www' server apart from the intuitive 'neatness' appeal?

• Update Windows using VB.net

  - by kagstrom2100

  I'm currently having my internship at a elementary school. I got the task to setup users for some classes, with that I also need run Windows Update too. So I have been scanning Google for something that does this in vb.net since I have been coding some in that before. I din't find much on the subject except for "C:\Windows\System32\wuauclt.exe /detectnow" though when I run it it don't seem to do much. So the question is it there is any command or file you can run to make Windows download and install updates? To clarify it need to work on Windows 7, I'm also writing the program in .NET 3.5. Please let me know if you need any more information! Thanx in advance :)

• Searching for online database software/cms

  - by ButterdBread

  I am searching for a software or CMS that manages and displays large online databases, as some kind of frontend to MySQL or any other database. It should be accessible through the browser, be as secure as possible (offering login). The data I'd like to store would be personal information such as name, adress and birthday - also I'd need to be able to add custom fields as well. Also forms and the possibility to download the data in an excel? table would be great. PHPmyadmin is not an option, it should be similar to a CRM but more closely adapted to managing database tables, searching for entries and filtering data. It should be possible to have many user accounts with different rights, with each of them being able to acces certain parts of the data and entering own data. Is there something out there, that might get close to what I imagine? I appreciate any help!

• Reverse Proxy Server SSL?

  - by valveLondon

  Context We currently have an Apache web server in the DMZ set up as a reverse proxy and load balancer for two machines running Windows Server 2008 (IIS) inside. The Apache server has a genuine SSL certificate and serves up both http and https, however, the balancer members in the load balancing section are set to: BalancerMember {https://server1} and {https://server2}. The IIS web servers have self-signed certificates in order to respond to the https requests. My question: Do we need to forward any requests from Apache (in the DMZ) to the inside using SSL? e.g can the reverse proxy forward the requests using HTTP? and if so, why would I choose to forward them with SSL? (how secure is the http line between the dmz and the inside); In other words, can I totally disable SSL on my inside web servers?

• Cannot SSH into Virtual Machine

  - by MasterGberry

  I am running a CentOS VM on my desktop that I use for development testing when coding in python. At my school I have a dedicated IP setup for the VM and my desktop so I never seem to have an issue ssh'ing from desktop into VM. I am now at home for winter break and cannot seem to SSH into the VM using the local ip address behind my router, the external IP with port 22 forwarded to my VM, or anything. Strangely enough I can ssh into my production server and then fromt here ssh into the VM, but not from my desktop to the VM directly What should I do to get this to work? Thanks

• Disabling certain JBoss ports

  - by Rich

  We are trying to configure JBoss 5.1.0 to be as lightweight and as secure as possible. One of the parts of this process is to identify and close any ports we do not need. Three ports that we have outstanding but don't believe we need are: 4457 - bisocket 4712 - JBossTS Recovery Manager 4713 - JBossTS Transaction Status Manager We don't think we need any of these features (but could be wrong). Bisocket seems to be a way for JMS clients behind a firewall to communicate with JBoss. We hardly use JMS now and when we do, it is very unlikely that we will need this firewall traversing ability. I am less sure about whether we need the two JBossTS ports - I am guessing these are used in a clustered environment - we aren't clustered. So my question is, how do we disable these ports (and associated processes where possible), or if we need these ports, why do we need to keep them open?

• Activating ssl on tomcat

  - by toom

  I want to encrypt the http traffic on a tomcat instance via ssl. Therefore I followed the most simplistic approach described on various webpages. But anyway it simply does not work. Here is what I did: "keytool -genkey -alias tomcat -keyalg RSA" and I enterd "changeit" as the password (since this is the defaut chosen by tomcat) Altering $CATALINA_HOME/conf/servers.xml by uncommenting the following line Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS"/ Restarting tomcat Entering https://localhost:8443 does not work. However, I can still access the page via normal http like http://localhost:8080 The logfile does not contain any suspicious information. What is going wrong here?

• Increase Volume of an MKV Video from Linux Terminal

  - by The How-To Geek

  I've got a large amount of .MKV video files which seem to all play at a very low volume - I end up having to turn the TV up all the way to hear them, which is really irritating when I switch to another channel and wake the dead because it's so loud. What I'm looking for is a command-line method to increase the volume (so I can run it on all of them quickly) that would hopefully work regardless of the audio codec in use in the particular file. (I don't mind hard-coding the output audio though). For reference, I'm using Ubuntu 9.04 on my server, and the files are being played back with Boxee on a Mac Mini, but the volume problem is the same on Windows too.

• Can I filter multiple column headers to display subheadings of each in Excel?

  - by Gigi

  I can't seem to find this anywhere... it may not even be possible without coding? I have a spreadsheet containing more than one heading in a single column. These headings are identified with blue background and white font. Each of these headings have items listed below them. These "subheadings" are smaller, auto-black font and no fill background. Currently I have to scroll down the spreadsheet to view all headers and their contents. How do I create a filter that would allow me to sort on whichever header I want, so that (only) the contents of that particular header are displayed?

• Controlling access to my API using SSH public key (not SSL)

  - by tharrison

  I have the challenge of implementing an API to be consumed by relatively non-technical clients -- pasting some sample code into their WordPress or homegrown PHP site is probably as much as we can ask. Asking them to install SSL on their servers ain't happening. So I am seeking a simple yet secure way to authenticate API clients. OAuth is the obvious solution, but I don't think it passes the "simple" test. Adding a client id and hashed secret as a parameter to the requests is closer -- it's not hard to do md5($secret . $client_id) or whatever the php would be. It seems to me that if client requests could use the same approach as SSH public keys (client gives us a key from their server(s) there should be some existing magic to make all of the subsequent transactions transparently work just as regular HTTP API requests. I am still working this out (obviously :-), so if I am being an idiot, it would be nice to know why. Thanks!

• Is disabling password login for SSH the same as deleting the password for all users?

  - by Arsham Skrenes

  I have a cloud server with only a root user. I SSH to it using RSA keys only. To make it more secure, I wanted to disable the password feature. I know that this can be done by editing the /etc/ssh/sshd_config file and changing PermitRootLogin yes to PermitRootLogin without-password. I was wondering if simply deleting the root password via passwd -d root would be the equivalent (assuming I do not create more users or new users have their passwords deleted too). Are there any security issues with one approach verses the other?

• Running a service as root

  - by kovica

  I have a java program that I use to automate the process of creating VPN settings for clients. The program calls couple of bash scripts, create and copies files around. I have to run it under root user because the whole VPN config is under /etc/openvpn. For this directory I need root privileges. On the same machine I have Glassfish application server and it will call the mentioned Java program. Glassfish is run under non-root user. What is the best, most secure way of running a program as a root user of course without entering a password if I run it via sudo?

• Can I get some help on a javascript project?

  - by HenryOrrin

  I'm learning javascript and I thought it would be fun to build a "simple" calculator. I spent a few hours coding, and implementing the functions, but it only works partially. Can one of you look at my code and try and figure out what's wrong? The Calculator.zip Here's some explanation of the issues: the add(), subtract(), multiply(), and divide() methods work partially, not at all, or don't do as they're supposed to.. sometimes the 0 wont clear when the replaceDisplay() method evaluates the screen. If it helps, I'm also using jquery, so keep that in mind. Thank you!

• What does the NTFS encryption protect against?

  - by Ray

  I have encrypted a folder from the (PropertiesAdvancedEncrypt contents to secure data). However when I change my user profile to another one which is also an administrator the folder seems to be accessible as if nothing happened. What exactly does this encryption protect against. I'm looking to encrypt folders that no other user, or another OS or even if the HDD were to be removed and plugged to another device will be accessible. My OS is Windows 7 Ultimate. Any suggestions?

• iptables to allow input and output traffic to and from web server only

  - by Caedmon

  I have an Elastic Search server which seems to have been exploited (it's being used for a DDoS attack having had NO firewall for about a month). As a temporary measure while I create a new one I was hoping to block all traffic to and from the server which wasn't coming from or going to our web server. Will these iptables rules achieve this: iptables -I INPUT \! --src 1.2.3.4 -m tcp -p tcp --dport 9200 -j DROP iptables -P FORWARD \! --src 1.2.3.4 DROP iptables -P OUTPUT \! --src 1.2.3.4 DROP The first rule is tried and tested but obviously wasn't preventing traffic coming from my server to other IP addresses so I was hoping I could add the second two rules to full secure it.

• Fedora: "Login Incorrect"

  - by darkblackcorner

  I've just set up a minimal install on my netbook (the default was too resource hungry, so I figured I'd customize the install and learn something about linux at the same time!) No problems logging in as root, but when I create a new user and try to login as them I just get the "Login incorrect" error. I'm certain the password is correct, though the secure log displays an authentication error. Am I missing a permission somewhere? useradd test usermod -p [pwd] test Shell is added automatically I think (checking password file says shell is /bin/bash) I've tried adding the user to the sudo-ers group usermod -a -G wheel which doesn't help. I've kept the password simple in order to rule out human error.

• Set up homeserver with single IP to host multiple sites on Ubuntu [closed]

  - by Ortix92

  I am trying to set up my homeserver so it can function as a regular server one would rent. I am running Ubuntu 12.04 LTS with openpanel. I have a single static IP address. I am used to having two addresses and pointing them to NS1.domain.tld and NS2.domain.tld and setting up the propper DNS records. I would also like to mention I am somewhat new to DNS zones. Either way, how would I go about setting this up correctly (in openpanel) with just a single IP address if possible at all? I have also read about free solutions online, but I would like to keep everything secure and private so other people can't peer into my data somehow. Thanks!

• Server 2008 Hyper-V User Accounts to access each other

  - by asn1981

  Hi, I have a windows server 2008 r2 with 3 hyper-v vm's IIS server Sql server 3 - Mail server I'm new to networking/server configuration. I have created a Virtual Network and can see each of the 3 VMs as well as the host on the network. I can connect from each VM to the host using the admin account. However, what would be the best (secure) way to create connections/accounts between the VMs, presumabely this shouldn't be done with an admin account but one with lesser priveledges. For example, to be able to access the SQL Server VM from the IIS server VM?

• a safer no password sudo?

  - by Stacia

  Ok, here's my problem - Please don't yell at me for being insecure! :) This is on my host machine. I'm the only one using it so it's fairly safe, but I have a very complex password that is hard to type over and over. I use the console for moving files around and executing arbitrary commands a LOT, and I switch terminals, so sudo remembering for the console isn't enough (AND I still have to type in my terrible password at least once!) In the past I have used the NOPASSWD trick in sudoers but I've decided to be more secure. Is there any sort of compromise besides allowing no password access to certain apps? (which can still be insecure) Something that will stop malware and remote logins from sudo rm -rf /-ing me, but in my terminals I can type happily away? Can I have this per terminal, perhaps, so just random commands won't make it through? I've tried running the terminal emulations as sudo, but that puts me as root.

• Remote Destkop into Server 2008R2 with Firewall On

  - by Eternal21

  I've got a fresh install of Remove Server 2008 R2, 64 bit. The problem is I can't Remote Destkop into it. I clicked 'Enable Remote Desktop' inside 'Initial Configuration Tasks', and set it to: Allow connections only from computers running Remote Destkop with Network Level Authentication (more secure). The thing is, this used to work just fine, and then it stopped. The only way I can get it to work now is if I turn of Windows Firewall completely off (Public network location settings). Obviously I don't want to run the server with firewall off, so what specific settings in Firewall do I need to disable, or am I doing something wrong?

• need help setting up a VPN for remote computer connection

  - by Chowdan

  I am on a low budget right now. I am currently in the process of starting a computer company. I am in need of a VPN network so I can run Dameware tools for working on customers/partners computers remotely. I will be working with Windows and some Apple and linux machines. I have desktop with an AMD Phenom II 965BE(currently running stable at 3.8Ghz) processor with 8 GB of ram and a radeon hd 6870(i know graphics aren't too useful) and about 1.5TB of HDD space. I am attempting to create a network out of my office based all on one machine that would also be secure for me to remotely connect to my partners computers so when they have issues I would be able to connect and do the diagnosing and repairs remotely. What types of servers besides a VPN server would i need to create this? I have access to all Microsoft products so I can run Windows Server 2012, Windows Server 2008 R2, or any other Microsoft Software. thanks for the help all

• Program for scanning, saving and restoring window position?

  - by hellbell.myopenid.com

  Is there some program for scanning, saving and restoring last window position? For example at this moment i have opened five window first is google chrome which is not opened at full screean but at half of display, second is notepad which is on right side, and third is cmd which is under notepad. So I want to use this combination of "layout" when primary using google chrome (surfing at internet), but if working primary at other program let's say word (writting text) i want to use other program and at different position (cause is effectivly). So the point is to easy switching from one "layout" to another. (Like in many program that support more modes, for example visual studio - debug layout, - coding layout, etc ...)

• Managing client passwords

  - by HurkNburkS

  I am just starting up a small website development business and one of the issues I am having is remembering passwords and account information for clients hosting, cpanel, ftp accounts etc. I was wondering what is the most suitable system / industry standard for controlling such information? Pretty marginal on the close there... I read the FAQ and I felt list this could be a common issue for webmasters, its defiantly not a coding questions so stackoverflow is out of the question and its not a broad question its focused on one particular aspect of being a webmaster.
